Abstract
A stent deployment system includes a tubular member having a first end and a second end and a generally longitudinal opening between the first and second ends. The tubular member has an inner periphery sized to receive a stent therein. A plurality of apertures are disposed on opposite sides of the generally longitudinal opening. An elongate retainer is removably receivable within the apertures to retain the stent in the tubular member and to release the stent from the tubular member when removed from the apertures.
Claims31
A stent deployment system, comprising:
- a tubular member having a first end and a second end and a generally longitudinal opening between the first and second ends, the tubular member having an inner periphery sized to receive a stent therein and further comprising
- a first branch portion,
- a second branch portion, and
- a trunk portion coupled to the first and second branch portions;
- a stent received within the inner periphery of the tubular member;
- a plurality of apertures disposed on the tubular member;
- and
- an elongate retainer removably receivable within the apertures to retain the stent in the tubular member and to release the stent from the tubular member when removed from the apertures.
A stent deployment system, comprising:
- a sheet of pliable material foldable into a stent receiving shape having a trunk portion and first and second branch portions;
- and
- a retainer disposed relative to the sheet to selectively retain the sheet in the stent receiving shape and release the sheet from the stent receiving shape.
A stent deployment system, comprising:
- a first branch sheath sized to receive a stent;
- a second branch sheath sized to receive a stent;
- and
- an elongate deployment actuator, coupled to the first and second branch sheaths and actuable to move the first and second branch sheaths from a stent retaining position to a stent deploying position.
A method of deploying a stent at a stent deployment site in a bifurcation within vasculature, the method comprising:
- providing a stent having first and second branch portions disposed within first and second branch sheaths;
- advancing the first and second branch sheaths, with the first and second branch portions of the stent disposed therein, within the bifurcation;
- advancing the first and second branch sheaths distally off of the first and second branch portions of the stent exposing the branch portions of the stent to the vasculature;
- and
- deploying the first and second branch portions in the bifurcation.
The method of claim 39 and further comprising:
- withdrawing the first and second branch sheaths proximally through the deployed first and second branch portions of the stent.
